Recent remarks related to the July 29 death of Landon T. Clay
suggest a review of a notable figure associated with Clay.
From a 2006 obituary of mathematician George Mackey —
"A deep thinker whose work in representation theory,
group actions, and functional analysis helped
bring closer together the fields of math and physics,
Dr. Mackey died March 15 of complications from
pneumonia. He was 90, had lived in Cambridge, and
was Landon T. Clay professor emeritus at Harvard University."
— Bryan Marquard, Boston Globe, April 28, 2006
